Ser Morgil Hastwyck was a knight who lived during the reign of King Aegon IV Targaryen. He was renowned for slandering Queen Naerys Targaryen and being confronted by her brother, Prince Aemon the Dragonknight, in trial by combat. According to Grand Maester Kaeth's Lives of Four Kings, these accusations were instigated by Aegon IV himself, who was at the time quarreling with his son and heir, Prince Daeron.
